lp-lab1-branch-and-bound

Implementation of Branch-n-Bound algorithm for Max Clique Problem via cplex-solver

For tests execution run command:

    python run_test.py

For certain benchmark execution run (e.g. benchmarks/DIMACS_all_ascii/C125.9.clq):

python main.py --filepath benchmarks/DIMACS_all_ascii/C125.9.clq
